Unintended pregnancy remains a worldwide problem in both developed and developing countries. In 2001, 49% of pregnancies in the United States were unintended. Moreover, more than 6 million women annually are at high risk of becoming unintentionally pregnant because of a gap in contraceptive use, and disadvantaged women are more likely to have more difficulty than others with continuous method use. Multiple strategies have been explored and implemented to increase the effective usage of contraception, including promoting the use of longer acting reversible contraceptives.
